The clinical evaluation in the "dystonies of function" or "impaired dexterity" reveals certain physical anomalies which either appear spontaneously or are triggered by specific tests: abnormal postures involving the trunck, head, and upper limb. During the professional gesture the physiological "pulley effect" on flexor tendons is accompanied with an interference effect produced by the displacement of the segments; this, adds up to an unbalance of the digital kinetic chain, building a locked functional system. The antagonist muscles begin to supply the deficiency of the agonist muscles. In addition, patients with a characteristic psychological ground suffer a more acute "disorganization" or a performing career.
在“功能障碍性肌张力障碍”或“灵活性受损”中的临床评估揭示了某些身体异常，这些异常要么自发出现，要么由特定测试引发：涉及躯干、头部和上肢的异常姿势。在专业手势过程中，屈肌腱上的生理“滑轮效应”伴随着节段移位产生的干扰效应；这导致手指动力链失衡，形成一个锁定的功能系统。拮抗肌开始补充主动肌的不足。此外，具有特定心理背景的患者会遭受更严重的“功能紊乱”或职业生涯受挫。
